• Only fit good-quality wiper blades.
• When removing an old wiper blade, note how it is fitted. Fitting new blades can sometimes be tricky, and noting how the old blade came off can save time.
• While the wiper blade is removed, take care not to knock the wiper arm from its locked position, or it could strike the glass.
• Offer the new blade into position the same way round as the old one. Ensure that it clicks home securely, otherwise it may come off in use, damaging the glass.
If smearing is still a problem despite fitting new wiper blades, try cleaning the glass with neat screenwash additive or methylated spirit.
Check the condition of the wiper blades; if they are cracked or show any signs of deterioration, or if the glass swept area is smeared, renew them. Wiper blades should be renewed annually.
To remove a windscreen wiper blade, pull the arm fully away from the windscreen until it locks. Swivel the blade through 90º, then depress the locking tab (arrowed) and push the blade down the arm.
Detach the blade from the end fitting on the arm. When fitting the new blade, make sure that the blade locks securely into the arm, and that the blade is orientated correctly.
Don’t forget to check the rear wiper blade(s) as well (where applicable) which are removed in the same way.
